NESAS Auditors and Test Laboratories
Audits and evaluations are a key component of the scheme, providing vendors with important feedback on how to improve their processes and products. As such, the organisations involved play a key role in enhancing security across the whole industry.
Becoming an Authorised Auditor
To ensure these are the best qualified and most professional auditing companies, we periodically conduct a competitive tender for the provision of NESAS auditing services. Selection criteria is agreed by the GSMA NESAS Oversight Board.
If you would like to know more or speak to someone about GSMA NESAS, please get in touch.
Becoming a NESAS Test Laboratory
All test labs we work with have undergone ISO/IEC 17025 accreditation and are competent to undertake security evaluation of network products, against relevant Security Assurance Specification (SCAS) documents.
Any network security test laboratory experienced in IT or network and telecommunications security testing can apply.
